Hi Ari,
Quoted 1 line
Can I use recvfrom and sendto with l2cap sockets (instead of listen,=20

accept,=20

Quoted 9 lines

connect,...)?
why do you repeat your emails? I already told you to try it and tell if it doesn't work.

Hi,

Sorry about that. The reason: I sent the message to the list, and waited fo= r=20
it to appear to my mailbox. It didn't appear and then I realised that I am = not=20
even subscribing the list. I thought that the message didn't get to the lis= t=20
and I posted it second time.

I have tried to use sendto this way:

int sock;
struct sockaddr_l2 sock_addr;
char addr[18] =3D "00:12:37:46:bc:2b";

sock =3D socket(AF_BLUETOOTH, SOCK_DGRAM, BTPROTO_L2CAP); sock_addr.l2_family =3D AF_BLUETOOTH;
sock_addr.l2_psm =3D htobs(6001);
str2ba(addr, &sock_addr.l2_bdaddr);
sendto(sock, "Bluetooth test", 15, 0, (struct sockaddr*)&sock_addr, sizeof (sock_addr));

sendto returns 'Invalid argument' error.

the SOCK_DGRAM support in L2CAP is not really good and thus might don't wanna you sendto() at all. Are there any problems with binding and connection to an L2CAP channel?
